WessB, I like to follow the basic recipe that was in Dr. BBQ's first book. I have never used the exact ingredients, my my modification has always been well received. Cut the Sweet Potato, lengthwise, into fourths. Coat with EVOO. Mix your favorite BBQ rub 50/50 with brown sugar and coat the cut sides of the potato. Form the pieces back together and wrap in heavy foil and cook at 350-400. Coook until very soft. Time is going to depend on size, but figure on around 1.5 hours for a tater big enough to feed two.
